I am using Ruby on Rails and need to read the contents of an xml file into an array?
I pulled the data from an API using the following:
uri = URI.parse("myAPIurl.com&show=storeID,name")
http = Net::HTTP.new(uri.host, uri.port)
request = Net::HTTP::Get.new(uri.request_uri)
response = http.request(request)
Looking for a lean method to iterate this xml file into an array using Ruby on Rails.
For simple use cases you can use:
xml = <<-XML
<?xml version="1.0" encoding="UTF-8"?>
<hash>
<foo type="integer">1</foo>
<bar type="integer">2</bar>
</hash>
XML
hash = Hash.from_xml(xml)
# => {"hash"=>{"foo"=>1, "bar"=>2}}
Try using Nokogiri gem. It's super easy to use, the website has some nice examples.
require 'open-uri'
doc = Nokogiri::HTML(open("myAPIurl.com&show=storeID,name"))
you can then query your document using xpath or css selectors. It then returns a NodeSet that you can iterate over like you would do with an array
Hope it helps
